JOHN S. RUIDZINSKI, OF PERRY, NEW YORK.

LINK-PAIDLOCK.

Application filed March 27, 1917.

To all whom it may concern:

Be it known that I, J OHN S. RUDZINSKI, a citizen of the United States, residing at- Perry, in the county of Wyoming and State of New York, have invented certain new and useful Improvements in Link-Padlocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a padlock and has for one of its objects the provision of a novel form of shackle having its ends rela tively spaced to permit the insertion of a member, which is to be locked and the space adapted to be closed by means carried by one of the ends of the shackle and adapted to engage the other end.

Another object of this invention is to provide a movable locking barrel upon one end of the shackle and adapted to be moved in engagement with the other end of the shackle to close the space occurring between the ends of the shackle.

A further object of this invention is to provide means for holding the barrel against movement when in a position closing the space occurring between the ends of the shackle.

A further object of this invention is to provide means formed upon the barrel for receiving a key whereby upon insertion of the key, the barrel will be freed from one end of the shackle and permitted to slide thereon for opening the space occurring between the ends of the shackle.

A still further object of this invention is the provision of a link padlock of this character, which shall be simple, durable and etlicient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists or" certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

Referring in detail to the drawing, the numeral. lindicates a shackle which is in the formation of a link providing an enlarged curved portion 2, which forms a space 3 for receiving the member which is to be locked. The ends of the shackle 1 are relatively spaced to form an entrance 4 to the space 3. One end of the shackle 1 is so bent as to form a straight portion 5, which has a plurality of recesses in which are slidably mounted pins 6, which are normally urged out of the recesses under the influence of coiled springs 7. A sleeve 8 of cylindrical formation is slidably mounted upon the straight end 5 of the shackle 1 and has a series of vertically arranged openings 9 which are adapted to receive the pins 6. The sleeve 8 is provided with a vertically eX- tending slot 10 opening outwardly through the bottom end thereof and is adapted to receive a lug 11 formed upon the straight end 5 of the shackle 1 when the device is being moved to an unlocked position, which will be hereinafter more fully described. A. projection 11' is formed upon the lower end of the sleeve adjacent the slot 10 and is adapted to engage the lug 11 for limiting the movement of the sleeve upon the straight end 5 oi the shackle 1 in one direction.

Surrounding the sleeve 8 is cylindrical locking barrel 12 having a series of vertically arranged apertures 13, which are adapted to register with the apertures 9 of the sleeve 8 and adapted to normally receive the outer ends of the pins 6 for locking the barrel against rotation upon the straight end 5 of the shackle 1. An oil'set portion 14 is formed upon the barrel 12 and has mounted therein key plug 15 having the usual key slot 16 for slidably receiving a key 17. Mounted within the key plug 15 and the openings 13 of the locking barrel 12 are a series of pins 18, engaging halls which are adapted to be engaged by the shank oi the key 17 when inserted within the slot 16 which causes the pin 18 to move the pins 6 rearwardly within the recesses of the straight end 5 of the shackle 1 against the tension of the springs 7. The pins 18 move the pins 6 within the recesses of the shackle sufficiently enough to permit the pins 6 to engage the apertures of the sleeve 8, thus freeing the sleeve and locking barrel 12 upon the shackle so that the same may be rotated thereon.

The end 19 of the shackle 1 has formed thereon an extension 20 that has formed thereon an elliptical shaped plate 21. The upper end of the locking barrel 12 has an inwardly directed flange 22, which has an elliptical shaped openin 23 adapted to re ceive the elliptical plate 21 when the locking barrel 12 and the sleeve is moved upwardly upon the straight portion 5 of the shackle 1 and by turning the barrel and sleeve onequarter of a turn to the left the elliptical opening 23 is arranged at right angles to the elliptical plate 21 thus locking the barrel 12 to the end 19 ot the shackle, whereby the space a is closed preventing any member which may be located within the space 3 of the shackle from being withdrawn therefrom.

In operation, when desiring to unlock the aforedescribed padlock. the key 17 is inserted in the slot 16 and as the notches upon the shank of the key engage the pins 18, moves the pins in the direction of the pins 6 and as the pins 18 move, the pins 6 are compelled to move against the tension of the springs '7, thus moving the pins 6 out of the apertures 9 of the sleeve 8, freeing the sleeve 8 and the locking barrel 12 upon the straight end 5 of the shackle. By turning the locking barrel 12 to the right, the elliptical opening 23 is brought into alinement with the elliptical shaped plate 21. The sleeve 8 is compelled to turn with the looking barrel 12 owing to the pins 18 extending into the apertures 9 of the sleeve, caused by the notches formed upon the shank of the key 17. As the barrel and sleeve rotate upon the shackle, the slot 10 within the sleeve 8 moves in alinement with the lug 11 upon the shackle, which permits the sleeve and barrel to move downwardly upon the straight portion 5 of the shackle opening the space 4, so that a member positioned within the space 3 of the shackle may be withdrawn therefrom or the member may be inserted through the passage 4 to the space 3.

When desiring to lock the shackle or close the space 4:, the barrel 12 is moved upwardly accompanied with the sleeve 8, owing to the fact that the sleeve 8 is locked to the barrel by the pins 18 until the elliptical shaped plate 21 is received within the elliptical opening 23 of the barrel 12. The barrel l2 is then turned to the right accompanied with the s1eeve8 arranging the elliptical opening at right angles to the elliptical plate 21, thus rorming a connection between the end 19 of the shackle and the barrel. As the barrel 12 is turned to the left, the sleeve 8 rotates therewith until the extension 11 engages the lug 11 upon the shackle, which limits the movement of the barrel 12 and the sleeve 8 to the left and simultaneously positioning the apertures 9 of the sleeve and the apertures of the enlargement 1% and slot of the straight portion 5 of the shackle 1 in alinement with each other so that when the key 17 is withdrawn from the slot 16, the pins 6 pass through the apertures 9 of the sleeve and into the apertures of the enlargement 1 1 of the barrel, thus locking the barrel and sleeve against rotation upon the shackle.

While I have shown and described the per- :Eerred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.
